Engineered by BMW for the naked motorcycle segment, the 2003 BMW R 850 R Classic features a 848 cc (51.7 cu in) two cylinder boxer, four-stroke configuration. In factory specification, peak output is rated at 70 HP (51.1 kW) at 7,000 rpm while maximum torque reaches 77.3 Nm (57 lb-ft) at 5,500 rpm. With a specific output of 82.5 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
